Abstract

An apparatus for use by a packet duplication control element or function, the apparatus including processing circuitry, and memory for storing instructions to be executed by the processing circuitry, wherein the memory and the instructions are configured to, with the processing circuitry, cause the apparatus at least: to receive assistance information indicating communication conditions of at least one communication link between a communication element and at least two communication network access points, to process the assistance information for preparing a packet duplication control, to generate transmission control information on the basis of the result of the processing of the assistance information, the transmission control information indicating settings for a packet duplication process in the established multi-connectivity communication, and to send the transmission control information to at least one transmission control element or function being involved in the packet duplication process in the established multi-connectivity communication.
